Zanzil's Secret is a neutral quest from Booty Bay in Stranglethorn Vale. In this quest, players are sent to collect samples of a mixture created by the exile Zanzil which causes those who drink it to become strong but feeble minded - similar to zombies.

The creatures which drop [Zanzil's Mixture] can be found at both the Ruins of Jubuwal (Coordinates 35,51) and the Ruins of Aboraz (Coordinates 38,57) northeast of Booty Bay. Many players report a much better drop rate at the Ruins of Aboraz, in addition to less tightly packed mobs. The monsters at Ruins of Jubuwal are in groups and it is difficult not to get swarmed. Aboraz is along the coastline, reachable either by beach or by a path leading east from the road, just south of Jubuwal.
